I believe investors should invest for the long run, so I don't buy and sell. I usually maintain the classic index of global equities, diversified U.S. and global and emerging markets, and when the risk is larger, I diminish the amount in global equities and put more into liquid assets - but very irregularly.

We're essentially continuing a system where profits are privatized and...losses socialized.

If we didn't have greed, market economies wouldn't be as innovative as they are. But in my view, greed has to be contained by the fear of losses, so there has to be a system where, if you take too much risk, you go into bankruptcy. You don't systematically bail out people who take excessive risks.

The global financial crisis - missed by most analysts - shows that most forecasters are poor at pricing in economic/financial risks, let alone geopolitical ones.

I believe, unlike people that are totally free-market, laissez-faire fundamentalists, that there is an important role that the government can play - one, in providing public goods, whether it's education, health care, or other things, and two, supervising countercyclical policy - stimulus, whether it's monetary, fiscal, or otherwise.

If you worry about financial Armageddon, it is indeed metaphorically the time to stock your bunker with guns, ammunition, canned food and gold bars.

The Treasury plan is a disgrace: a bailout of reckless bankers, lenders and investors that provides little direct debt relief to borrowers and financially stressed households and that will come at a very high cost to the US taxpayer. And the plan does nothing to resolve the severe stress in money markets and interbank markets that are now close to a systemic meltdown.
